Abstract

An aftertreatment module includes a catalytic brick having upstream and downstream flanges sized to extend over potential leak flow paths between bricks. Additionally, an aftertreatment module has an array of similarly flanged bricks to reduce leakage through all interfaces between adjacent bricks. A frame for holding the array of bricks includes flow modulators to restrict leakage through an interface between the frame and at least one side surface defined by the array of bricks.
